DatagraphiX manufactured and sold computer graphics equipment that allowed users to transfer large volumes of information directly from computers to microfilm. Customers were required to keep maintenance documentation onsite for the DatagraphiX service personnel. The service manual carried this legend: “No other use, direct or indirect, of this document or of any information derived there from is authorized. No copies of any part of this document shall be made without written approval by DatagraphiX.” In addition, on every page of the maintenance manual, the company placed warnings that the information was proprietary and not to be duplicated. Frederick J. Lennen left DatagraphiX to start his own company that serviced DatagraphiX equipment. Can DatagraphiX prevent Lennen from using its manuals?
